Welcome
A PC can only be found in the US, and if you should be able to get it in the Netherlands,you have the 110Volts-issue.
Long story short you need to look at for example the Makita BO6040 and the other random orbit sanders with velcro backingplates to replace a PC.
As for Zaino:you can order that via:
www.viper-lifestyle.de:
very reliable and relatively fast (about 4 work-days after payment)
as for
Meguiars:you can look on their website for local distributors(
www.meguiars.com)
3M should be available in allmost any auto-store(swirl & scratch removers bodyshop proof
)
Haven't found distributors for
Klasse,Mothers,Blackfire,...in Europe
Hope that answeres some Questions
Happy detailing
